Application filed September 16, 188B. Serial No. 213,686. (No model.)

To all whom t may concern:

Be it known that I, HEMAN A. BARNARD, of the town of Moline,in thecounty of Rock Island and State of Illinois, have invented certain newand useful Improvements in Smut-Mills; and I do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accompanying drawings, and to the letters of 1oreference marked thereon, which form part of this specification, in'which- Figure l is a perspective view of a machine embodying myimprovements.

This invention relates to improvements in grain-scourers, or smuttersand separators;

3o and its objects are to construct a machine which will quickly andeffectually remove foreign matters and impurities from the grain treatedtherein, and the mechanism of which may be driven at will in alternatedirections,

and in which the discharge of grain may be readily adjusted or reversed,so as to conduct the. cleaned grain to either side of the mill.

The invention consists in the construction and novel combination ofparts hereinafter 4o described, illustrated in the drawings, and

particularly specified in the claims.

Referring to the drawings by letter, A designates the mainsupporting-frame of the machine, of general rectangular shape, as shown,

and carrying the fan-casing a and the casing c', inclosing the scouringmechanism, hereinafter described.

B is the main or driving shaft, passing centrally through the fan andscouring casings 5o and carrying the driving-pulley l), which can besecured at either of its ends. The said pulley is driven by a properbelt from any suitable source of power. The shaft B turns injournal-boxes C, secured to the horizontal end bars C', bolted to themain frame A, andl 55 each box is composed of a rectangular block c,which rests between vertical flanges c on bar C', and a cap-piecesecured to the block c over shaft B by proper bolts, as shown in Fig. 5.The boxes C are Yrendered horizon- 6o tally adjustable by means ofscrew-bolts c2, which pass through threaded openings in iianges c andimpinge upon the ends of the boxes, and are made vertically,adjustableby means of the bolts c3, which pass through the outstanding i'langes ofbars C and bear upon the bottoms of the boxes.

H is the fan secured to shaft B and rotating in its casing a, situatednear one end of the main frame. The casing a is provided 7o with theexit-opening h, as shown in Fig. 1, for the escape of air from saidcasing. The blades h of fan I-I are secured to the-arms thereof, so thatthey will lie in planes passing radially through the main shaft, so thatthey will produce currents of air of equal force in the same direction,whether the fan turns to the right or to the left.

H is an air flue or trunk opening into the fan-casing around the shaftB, as shown in vv8o Fig. 3, thence extending upward to and bendinghorizontally over the top of the main frame.

I, Figs. 3 and 4, is a detachable casing secured to the top of the mainframe at right angles to the horizontal portion of flue H. The casing Ihas at one end the downwardlyextending tube or trunk I depending fromvcasing I on one side of the main frame A, and the casing is divided byahorizontal lon- 9o gitudinal partition t' into upper and lower`compartments, as shown. The outer part of partition i' inclines'downwardly toward the front wall of the part I of the casing I, andforms, with the vertical outer wall of said part, the triangularsettling-chamber 1l', having at its lowest point an opening closed by avalve d2, hinged at its upper edge. The outer part of wall I below saidchamber inclines inward a short distance, and then runs loo verticallydownward to meet the inclined inner wall 5 of the casing, as shown. Bythisl construction I form a second settling-chamber I3 in part I belowchamber '11', which is also provided with a hinged valve t".

The upper compartment of casing I is divided into upper and lowerair-tlues .I J by the horizontal partition j, the outer end of whichinclines downward a short distance into settling-chamber i', as shown.The airiiues .I J consequently communicate at their outer ends in theupper portion of said cham The lower compartment of casing I is dividedinto upper and lower air-fines K K by the horizontal partition 7.3, theouter end of which inclines downward a proper distance parallel with theinclined front end of partition il, as shown, so that the air-flues K Kcommunicate at their outer ends above chamber i3, but below the bottomof iiue K', as shown. The iiue K is extended beyond the casing Iopposite part I and communicates with the upper end of avertical trunk7c', suitably secured to the main frame.

rlhe casing I and trunk 7c are secured to frame A in any well-knownmanner, so that they can be easily detached therefrom and from eachother, when desired, for the purpose of reversing the position of theseparts in relation to the rest of the machine, as shown in Fig. 4 bydotted lines, and hereinafter set forth.

`L L are similar opposite openings in the side walls of easing I,communica-ting with the flues J and K.

The air-trunk II connects at its upper horizontal end with the casing Iaround one set of openings I., as shown in Fig. 3, so that the filles Jand K communicate with said trunk. \Vhen in this position, the openingsI. on the opposite wall of casing I are closed by a suitable door I, asshown in Fig. 3.

Z is an opening in the roof of the flue J, forming a communicationbetween said flue and a trunk D, which I will now describe. The trunk Dis situated above casing I, and its vertical leg (Z is detachablysecured in any suitable manner to said casing and communicates with theiiue J thereof, as described. The frontleg d of trunk D opens into ascreenshoe E. This sereen-shoe is supported by suitable spring-strapse., (only one of which is showin) having their lower ends secured toopposite legs of frame A at one end thereof, and the screen is vibratedby a rod from an eccentric mounted on a shaft c, supported by andturning in bearings in the ends of standards rising from the top siderail of the main frame A, and rotated by means of a pulley c2 on theouter end of said Vsha-ft, driven by a belt c* from a pulley c4 on theend of shaft B. The upper open mouth of the screen-shoe E receives thelower end of the leg d of trunk D, and has secured toits edge, on oneside of said leg, the chute F, which surrounds the outer and side edgesof a hopper D', secured on the leg d of trunk D, as shown, so that grainpassing from said hopper onto the chute will be directed into the shoeE, and the es cape thereof from the hopper D outside of said chuteprevented, as shown in Fig. 2. The inclined bottom of chute F passesthrough a proper opening or recess j' in the inner side of leg d of thetrunk, which opening is regnlated in size by means of a vertically-adjustable valve or slide j", as shown, so that the amount of grainescaping from hopper D can be regulated.

f2 is a cant-board extending from the same side of the shoe, parallel tobut wider than the inclined bottom of chute F, so as to throw the grainupon the head or upper part of the oppositely-inclined screen or sieveG, secured in the upper end or mouth of the screen-shoe.

G is a screen situated below the screen G, of finer mesh than the latterand inclined in an opposite direction, and extending the entire lengthof the shoe E.

g is a cant-board secured beneath and parallel to the screen G, but ofless length than the latter, and adapted to deliver the grain whichpasses through screen G upon screen G at its upper end.

G2 designates a still finer mesh screen, below and parallelto screen G',but extending only about half-way across the shoe, as shown, its innerend heilig secured to a suitable crosspiece secured centrally of theshoe, as shown in Fig. 2.

The hopper D being filled with wheat or other grain and the machine putin motion, the vibrations of the shoe will cause the wheat to fall fromthe chute F onto the cant-board f2, and is directed thereby to the headof the receiving-screen G, through which itfalls onto the cant-board g.The oats pars from screen G into the inclined gutter g at the end of theshoe, as shown in Fig. 2, whence they are conducted to any properreceptacle. From board g the wheat falls upon screen G', passingtherethrough, and any remaining coarse impurities are directed into thegutter g3 on the lower end of the screen to be conducted out of the way.The wheat falls from screen G onto screen G2, and any very fine impurities or grit pass through the screen and fall upon a chute g4, and areconducted out of the machine. The wheat, however, passes oit' screen G2upon a chute g2, which directs the wheat into a conducting-tube g5. Anywheat which may roll so far down screen G as to miss falling upon screenG2 will fall upon the chute g2 and be delivered to tube g5. The spout g5conducts the wheat to the scouringcase, hereinafter described, the lowerend'of said spout opening thereinto, as shown in Fig. The leg d of trunkD, that receives the wheat from the hopper, is open for the admission ofair as well as for the passage oi the grain into the screen-shoe.

From the foregoing description, and by reference to Figs. 2, 5, and 4,it will .be observed y that the fan II causes two distinct currents ofair to enter the machine, one of which currents passes up through theleg d of trunk IOO IIO

D, outward through fiue J, over the settlingchamber i', inward throughflue J', and then through opening L and down the flue I-I' to the fan.The other current passes up through flue lc', outward through the flueK', over settling-chamber i3, inward through i'lue K, and thence throughthe openingL and down the flue H' to the fan. The common exit of bothcurrents is through the opening h in the fancasing, as shown in Fig. l.Itis evident that' the upper current in entering the separatingtrunk Dpasses through the grain falling from the hopper, and carries With itthe dust and other light particles Which collect in the settling-chambert" until their Weight is sufficient to force Open the valve i2, whenthey fall out, and the suction of the current again closes the valve.The settling-chamber 3 and valve i4 act similarly for the secondcurrent, which collects the dust from the Wheat passing from thescourer, as hereinafter shown.

The casing d' has secured Within it the case N for the beater Q, formingthe scouring mechanism. The case N is preferably formed on the frustumof a cone, and is made, preferably, of chilled cast-iron, provided Withnumerous perforations on itsY periphery, and the main shaft B passesaxially through it, as shown in Figs. 3 and 4.

P is a flanged opening in the loWest part of the periphery of the case Nand adapted to connect with the upper end of the grain-de livering tubep. The sides of casing a' below case N converge longitudinally inward,as at n n, Fig. 4, andare each provided With a similar opposite openingO, adapted to be closed by a suitable door or cover O. The tube p hasits inner end connected with the case N, as described, and extendsthence through the opening O in the Wall n of casing a on the sideadjacent to trunk k' and connects With the trunk, as shown in Fig. 4.

The beater or scouring-cylinder Q is of the gen eral form of acone-frustum, and is secured on shaft B Within case N. The beater isprovided with the longitudinal equidistant pe-V ripheral flanges q, eachtriangular in crosssection and having an equal inclination on each side,so that they will have the same effect, Whatever be the direction ofrotation of the beater. The beater Q is preferably cast in one pieceWith its flanges q, as shown in Fig. 4.

The casing d' communicates with the faneasing a through opening 03, sothat the fan produces a third current of air, which passes up throughthe lower open end 02 of casing a', aroundthe case N, through sideopenings o3, into the fan-casing, as shown in Fig. 3. The sides offan-casing d converge toward opening h, as shown in Fig. 6, so thatthere will be no change in the direction of the air-currents if therotation of the shaft B is reversed. The grain falling into spout g5from shoe E is delivered into the scouring-case N, as shown in Fig. 3,and is violently agitated by the beater Q. The dust and other lightparticles which might adhere to the grain are driven through theperforations in case N into casing a', and carried by the air-currenttherein into the fan-casing a. The grain descending through pipe p intothe separating-trunk k meets the current of air passing therethrough,and any remaining dust and light particles, if any, are carried to thesettling-ehamber i3 and disposed of as described.

R is a valve in flue J, for regulating the upper air-current. The saidvalve is operated by the lever r on its hinge-rod outside the casing andcan be held in position by means of a curved slotted bracket r' andthumb-nut r2. The lowercurrent is regulated by a similar valve S in theflue K, controlled by a lever s and set by means of a bracket s' andthumbscrew s2.

Vhen it is desired to have the grain delivered from the opposite side ofthe machine from that described, as may be desirable in order toeconomize room or to adapt the machine for use in connection with othermilling devices, the casingl is disconnected from the trunks D and 7c'and from the fiue H' and removed from the machine. The trunk lc' is alsodisconnected from pipe p and removed. The casing I is then taken andplaced on the side of frame A formerly occupied by trunk la', and againconnected with thev trunk D and air-tube H', connecting With the formerby opening ZV', as before described, and with the latter by means of itsopenings L L', Which are unclosed, and the cover Z removed and used toclose the openings L L, which then occupy7 the same relative position toparts D and H as was formerly occupied by openings L'. The trunk k isthen attached to the machine in the former position of casing I andconnected therewith as before. The tube p is reversed and extendedthrough the opening O in the Wall n opposite its former passage, thesame being properly closed.

It is obvious from the foregoing that the machine is readily and quicklyreversible for the p'urpose described, and therefore the location of themachine need not be considered, as it may be placed in spots unsuitablefor machines running in one direction only; also, should thedriving-belt become slack, it could be crossed Without interfering Withor altering the action of the machine, although the motion of the fanand beater is thereby reversed.

If desired, the screen-shoe E can be dispensed with and the graindelivered direct from the hopper D' on the leg d' of trunk D into thespout g5, as is obvious.

If but one separation is desired, the trunk D, tlues J J',settling-chamber i', and screenshoe E are dispensed with and the grainde- IOO IIO

livered directly into the spout g5, reducing p trunk I), thescreening-casing, the fan and trunk II', with t-he detachable andreversible casing I, containing the air-tlues and the trunk K',substantially as and for the purpose set forth.
